declaresqlserverRevisestring

declare @level varchar(200)
declare @level_1 varchar(200)
set @level ='1|0#1#2#3'
set @level_1='1|0#3'

修改字符串set @level='1|0#1#3''或者set @level='1|0#1#2#3,2|0#1'

@level_1的值不變，

如果修改字符串set @level='1|0#1'則@level_1='1|0',

或者 set @level='2|0#1'則@level_1=''

即字符串二中的值必須是字符串一中有，如果字符串一沒有則字符串二沒有，但字符串一中有但字符二中不一定有
